How can I deal with `No enum constant` error in AWS Glue

Question

I am creating a JOB in AWS Glue but it shows below error in the last step.

{"service":"AWSGlue","statusCode":400,"errorCode":"InvalidInputException","requestId":"ad9ee511-adb8-11e9-9bbf-9d08424a9846","errorMessage":"No enum constant com.amazonaws.services.glue.FileFormat.UNKNOWN","type":"AwsServiceError"}

The column mapping is shown correctly as below screenshot.

what I don't understand is which input field has an invalid data? Glue doesn't give me more detailed information about this error. How can I debug this issue?

I faced the same issue, because accidentally I tried to write the data to my DynamoDB table (as my Target). When I changed to S3. It worked. You can learn more about it on AWS Documentation Here is the issue raised in amazon related to this.
